REFRIGERATION CIRCUITS Dual refrigeration circuits include high effi ciency hermetic scroll type compressors. Scroll compressors represent new yet proven compressor technology. Scroll compressors offer a combination of reliability, performance, and effi ciency. System noise is inherently quieter with scroll compressors. Scroll compressors offer: Simplicity - Fewer parts. Two components, a fi xed scroll and orbiting scroll, replace approximately 15 parts required to do the same work. Improved Starting Ability - With the scroll design the internal compression components always start unloaded even if the system pressures are not balanced. Since internal compressor pressures are always balanced at start-up, low voltage characteristics are excellent for scroll compressors. Energy Effi ciency - Scroll compressors are at least 10% more effi cient than reciprocating type compressors. The suction and discharge processes of a scroll compressor are physically separated. This reduces heat transfer between the suction and discharge gas. In a piston type compressor the cylinder is exposed to both suction and discharge gas. This results in high heat transfer reducing the compressor effi ciency. Scroll compressor compression and discharge processes are very smooth. Gas is compressed in approximately 1 1/ 2 revolutions compared to less than 1/ 2 revolution for a piston. Scrolls require no valves. Piston compressors require both suction and discharge valves. No valves, no valve losses. Durability - Signifi cant design effort and system cost are required to protect piston compressors from slugging and debris. Scroll compressors are designed to be more tolerant of both liquid and debris. Reliability - Scrolls contain fewer moving parts resulting in greater reliability. Proven performance means fewer maintenance calls for fi eld personnel. Lower Sound - Systems properly designed with scroll compressors will be inherently quieter. On average, the compressor is up to 5 decibels quieter. (Sound characteristics of a scroll compressor are different than that of a reciprocating compressor. These do not effect system performance or reliability) These durable, heavy duty compressors have no gaskets or seals, eliminating the possibility of refrigerant or oil leaking into the controlled space or environment. Each refrigeration circuit includes built-in compressor overload protection, crankcase heater, fi lter drier, sight glass, adjustable expansion valve with external equalizer, low pressure override timer (air cooled units), manual reset high pressure control, and anti-short cycle timer. Water/glycol cooled units include counterfl ow condensers sized to provide the required capacity for heat rejection with minimum water/glycol fl ow and total pressure drop. Head pressure regulating valves control 6
the condensing temperature and maintain required capacity at various water/glycol fl ow rates and temperatures. Air Cooled with Remote Outdoor Air Cooled Condenser A wide range of outdoor condensers are available with vertical air discharge. Condensers manufactured by Data Aire are sized to meet the required heat rejection and ambient conditions. The industrial duty condenser design includes an aluminum housing, aluminum fi nned copper tube coils, powder coated fan guards, energy effi cient, thermally protected direct drive motors, and variable speed fan control on the lead motor for proper control down to -20° F. Additional fan motors are controlled with ambient thermostats. Air Cooled with Indoor Condenser A wide range of fl oor mounted indoor condensers with horizontal intake and discharge are available for applications where an outdoor condenser cannot be used. Finished to match the indoor evaporator section, the condenser includes a centrifugal, forward curved, double width, double inlet blower engineered for quiet and reliable operation. The belt driven variable pitch drive section provides adjustable airfl ow. The motor has internal overload protection and is mounted on an adjustable slide base. Indoor condensers are provided with a factory mounted and piped receiver. The receiver has a head pressure control valve to maintain fl ooded condenser control. Air Cooled with Remote Outdoor Condensing Unit When compressors are required to be out of the controlled space, Data Aire Series units are available with a remote outdoor condensing unit. The condensing unit includes the compressors with built-in overload protection, crankcase heater, fi lter drier, sight glass, and condenser coil. The REFRIGERATION CIRCUITS, continued 7 condenser coil is constructed with copper tubes and aluminum fi ns. The housing is aluminum with vertical air discharge. The condenser is variable speed fan control on the lead motor for head pressure control down to -20° F. Additional fan motors are controlled by ambient fan thermostats. Water/Glycol Cooled with Remote Outdoor Fluid Cooler Remote outdoor dry coolers (fl uid coolers) are available in a variety of sizes. Each dry cooler includes an aluminum housing, aluminum fi nned copper tube coil, powder coated fan guards, surge tank, pump contactor, and energy effi cient, thermally protected direct drive motors. Dry coolers with multiple motors have cycling control. Water/Glycol Cooled with Indoor Fluid Cooler When required a wide range of fl oor mounted indoor fl uid coolers (dry coolers) are available. The air intake and discharge are horizontal. Units are fi nished to match the indoor unit. The centrifugal, forward curved, double width, double inlet blower is engineered for quiet reliable operation. The belt driven variable pitch drive section provides adjustable airfl ow. The fan motor has internal overload protection and is mounted on an adjustable slide base. The unit control panel includes a pump contactor (units can be ordered with a factory mounted pump).
